Abstract
A variety of quinolinecarboxaldehydes have been reacted with arenes in the Bronsted superacid, CF3SO3H (triflic acid) to give condensation products in good to excellent yields (52-99%). The quinolinecarboxaldehydes are signif icantly more reactive than 2-naphthalenecarboxaldehyde. It is proposed that the increased reactivity is due to the formation of dicationic, electrophi lic intermediates.
